計値の範囲内で適正に運転させることもできる。According to the third aspect of the present invention, by providing a bypass line that bypasses the power generator equipped with the in-line turbine and can supply water to the water receiving tank, the power generator equipped with the in-line turbine is protected from failure. In the event of an emergency or maintenance, it is possible to send water from the bypass pipe to the water receiving tank while stopping the water supply to the water pipe. In addition, by adjusting the opening of the bypass pipeline, or by controlling the decompression or the decompression / decompression control of the decompression means, it is possible to adjust the ratio between the amount of water flowing through the water pipeline and the amount of water flowing through the bypass pipeline. Properly install a power generator equipped with an in-line turbine within the design value range by avoiding the inconvenience that the equipment is overloaded with water flow exceeding the upper limit and the inconvenience of non-power generation with water flow below the lower limit. It can also be driven.
